I use:
blizz sorc for mf (it owns !)
barb for gf (boosted BO and defensive skills, the merc does the job)
200 fcr CB/FO sorc for keying: I'll try her for grushing, but I might go for a 200 fcr pure light sorc for keying
I have a NL uber smiter, but I'm playing L
I hope to make a blizz sorc for pvp

pure firebaal sorc with lots of points in teleport simply to run nightmare countess and nightmare andy for runes and hopefully one day a soj. She lvl 69 so she can craft with succes.
What else can a lvl 69 character do?

Strafezon, although I use multi more often, made to run mausoleum, pits and ancienttunnels. Can run wsk if there aren't gloam and fireball shooting physical immune things in the 3th level. Sadly she can't kill baal so actually, she stinks.

Rest, 4 mules, 1 cow runner on ladder that is idle at the moment, will become cow runner on nonladder once the ladder resets. And 1 character that is keeping the name stt_silence for when ever I get a selffound vex so that I can made my selfmade silence strafezon.

Light sorc without infinity - mf, keys, crafts (93lvl-highest in my DII career
Ice ama - used to be neat goldfinder, but she lagg servers badly doing anything with more than 1 player games
Gunslinger ama - currently main playable char, I'm struggling for Faith right now
Fury druid - for general pwnage...
Those were EuScL chars, I have also singleplayer hardcore wannabe-windy druid which I play only full clears, untwinked, no atma & /players8 - I recommend for those who want to spend more than 5 minutes to kill each boss:soapbox:

Lvl 90 Fanazeal Smiter Paladin for UT runs / Aimless Monster Pummeling, he's practically unbreakable as long as he's not IM'ed, have had multiple times of Diablo, Baal and Meph spawning bad and bashing him at the same time and he survived.
